**HELP** Need to understand trajectory(heavy VS light) in bullets.

Here's my question Guys in same bullets(accubond/accubond, VLD/VLD etc.) with one at 130grn and the other at 140-150 which bullet would shoot the flatest at longer ranges(300-700yrds etc)? I've always thought the heavier bullet would have the better trajectory at longer distance being the lighter would run out of steam. EXAMPLE as I look at same bullet trajectories here at federals website the heavier bullet is the one that drops the most. I thought different at LONGER range.

Federal Premium - Rifle Ballistics

Explain to me why do we use the heavier bullets as opposed to the lighter for long range. In ending I do understand wind drift in the lighter VS heavier, but trying to understand what's stated up top thanks!

popapi, There are other factors that come into play, other than just bullet weight. The most important of which is the ballistic coefficient of the bullet and the velocity at which it is fired. For example a .308 Win firing a 150 Rn bullet with a B.C of .227 @ 2800 fps and the same 308 firing a 150 HPBT Matchking with a B.C. of .417 at the same 2800fps. The Round nose bullet will drop 17.40inches from a 100yd zero while the Matchking will drop 13.62 inches because of it's ability to shed wind and retain velocity better. For long range hunting and match shooting it is the general consensus that it is easier to compensate for drop than it is for wind drift. All things being equal a heavier bullet with a high B.C. will drop a little more but drift less and retain more energy than a lighter bullet with the same B.C. There are a lot of more knowledgeable shooters here than myself and I'm sure that some can clear up the water,perhaps better than I. This is just a short synopsis, I hope it helped some.

Yes it did Chuck I understand stand this synopsis, but need help as to same bullet design just how the heavier would be the flatter at the distances I mentioned above.
